Description

Quick cooling system for bottom of calcining furnace

Technical Field

The utility model relates to a forge burning furnace equipment technical field, specifically a forge burning furnace stove bottom rapid cooling system.

Background

A calcining furnace is a thermal equipment for heat treatment of carbon raw materials (such as coke, anthracite and the like) at high temperature to improve the performance of the raw materials. The furnace types used for calcining carbon materials at home and abroad mainly comprise a rotary kiln, a pot type calcining furnace, a rotary bed calcining furnace, an electric calcining furnace, a coke oven and the like. These types of furnaces have significant differences in heat sources, heat transfer means, and calcination atmosphere due to differences in furnace body structures and process conditions. The pot calciner and the coke oven belong to the indirect heating type. The heat of the flue gas in the flue is transferred to the calcined material through refractory bricks serving as walls of the flue. Rotary kiln and rotary bed calcination are another type of direct heating. The high-temperature flue gas is directly contacted with the calcined material, and the burning loss of the carbon is larger than that of the former heating type which basically isolates air. The electric calcining furnace is used for converting electric energy into heat energy by taking a calcined material as a resistance heating body so as to realize self-heating of the calcined material.

The conventional pot-type calcining furnace bottom generally uses carbon bricks as main materials, is mostly of a single-layer brick structure, and is easy to crack due to the influence of cold-heat transformation when in use, poor in sealing performance, influences the quality of products, shortens the service life of a kiln, and causes low production efficiency.
